problem in cookie if dn contains a space

Hello,

My dn contain a space : "uid=user,ou=people,dc=my company,dc=com"

An internal error occurs because cookie can not contain a space. (raised in Cookies.py)

In order to make repoze.who.plugins.ldap working with my configuration, I had to changed the returned value of authenticate function when authentication.

return dn > changed to > return 'uid=%s' % identity['login']

It works with return identity['login']

In my case, i'm sure that uid is unique, so i can return uid as well as dn.
I had not found any other solution to make cookies work with a dn containing a space.
